In this programme, a primary school in St Albans called in Dick to cut their water bills. And in Cambridgeshire, mechanic Gary got a visit from Dick and Jim, who helped him make biodiesel for his four-wheel drive from take-away cooking oil.

Meanwhile, the Keenan family got their massive wind turbine, which will give them all the electricity they'll ever need. Watch them talk about their ambitious project.

In this programme, eco-campsite sisters Jake and Candy got their wind-turbine in Cornwall, but not before being tested by Dick on their knowledge of electricity.

In Lincolnshire, we met Zannah and Arthur who discovered that going green in a conservation area isn't easy. They've got their solar panel, but were they allowed to keep it?

In Somerset, we met the Warrens, who with Dick’s help, started sustainable livestock farming when they got their first Gloucester Old Spot pigs. Find out what's happened since the show in our video clip.

In programme four, James met Maggie, who was determined to decorate her 1930's house using eco-paints, while restoring and reusing the original features. Then in Northampton, the team helped Julie and her dad install a solar panel on the roof.

The programme also revisited the Keenans in Wirral. The guest-wing of their big eco-build was nearing completion. They got stuck in and learned how to use environmentally friendly lime plaster.

In programme three, Dick and James revisited would-be green gardeners Duncan and Steve to see how their urban garden was progressing.
Then in Cornwall, Dick learned the mysterious art of water-divining when he returned to the Moriaty family project to build an eco-campsite.
Dick, James and Jim also visited Chris and Carla Fletcher, who moved to rural Scotland to become more self-sufficient.

In programme two, Dick helped Duncan and Steve in Bath to give their scruffy city garden the green treatment. Using only free, recycled materials, they start building a greenhouse. Then in Cornwall, Dick helped the Moriaty family to build an eco-campsite.

In the first programme, Dick helped the Keenan family in Wirral build an eco-house, setting up a ground-source heat pump, wind-turbine, and rainwater harvesting system.
Then Dick, helped by James and assistant Jim, went to the aid of the Hunts family, who needed to grow fresh fruit and vegetables for their son who has multiple allergies.
